MutationObservers cannot observe 'checked' property of checkboxes.

When UI interactions affect native controls such as checkboxes, and fire an
onChange event; it is not guaranteed that MutationObservers see these
changes. Is there a reason behind this, or is it an oversight? This seems
like a common use case for MutationObservers as I first started working
with them.
